# Removed Features and Important Modifications

This page covers new features and modifications in version 3.0, compared to the previous release V2.1.

- Subscription Option
  The e-mail notification and subscription option, which was displayed at the first start in previous releases, has been removed. Please use the registration page if you are interested in getting all important announcements regarding uDraw(Graph).
- No Support for V1.1 Status Files
  uDraw(Graph) since version 3.0 cannot load status files written by the previous release V1.1 (this was the first public release in 1993). Loading status files written by V1.2 or later is still supported. You can determine the version of a status file by loading it in a text editor. The version is displayed at the beginning. Work-around: load the V1.1 status file in the previous release V2.1 and save the status there to load it in uDraw(Graph).
- Keyboard Control for Dialog Windows
  The keyboard control for dialog windows has been removed.
- Removed API Commands
  The API command set(no_cache(boolean)) has been disabled, because the function is no longer necessary. When sent to the API, this command will be ignored and answered immediately with ok. The commands graph(update(mixed_update)) and graph(update_and_change_attr(mixed_updates,attr_changes), where mixed_updates is a common list for both node and edge updates, have been renamed to graph(mixed_update(mixed_updates))) and graph(mixed_update_and_change_attr(mixed_updates,attr_changes). The former commands never worked reliable due to overloading conflicts with the commands of the same name that have different lists for node and edge updates.
- Removed Command-Line Options
  The command-line options -speedy and -nocache, relics from the early days, have been disabled. When used, these options will be ignored.
